Hi, Do your PU (Persistence Unit) names match (e.g. "default" in your persistence.xml and when you call createEntityManagerFactory("default", properties)) ?
Note: If you are using Eclipse it will automatically copy the files (e.g. persistence.xml and log4j.xml) in the src\META-INF directory to the war\WEB-INFO\classes\META-INF directory.
